Excuse, but haven't got sufficiant time to write down the whole stories.
That's a good start tho. Quite the contribution.
I can add this bit about James Dean, as it's not too far from where we live:
My wife and I had a silver Miata, and she would call me, not the car, "Little Bastard". And I think James Dean was a better driver than I.
We drove down to the coast and took an unusual route for us which brought use to the wreck site of James Dean. This is what it looks like today,
http://maps.google.com/maps?ll=35.734546,-120.28408&z=17&t=h&hl=en which is a modern, and confusing intersection. However, back in the day of James Dean, IIRC, this intersection was a simple three- way stop, a T intersection with one road ending at the major roadway. This monument to James Dean, is some bit down the road from the actual crash site.
http://maps.google.com/maps?ll=35.723365,-120.29702&z=17&t=h&hl=en The area is desolate, hot and dry during the summer. I can imagine James Dean being very tired after getting the car prepped for Monterey and driven up from So Cal that morning. No wind protection from little racing screen on the Porsche, buffed about in a probably twitchy car, were all things I recall when we stopped at the monument. I could easily see how sun glare played into the events that ultimately resulted in him being hit by a car twice the height ashis. The fact that there was even another car out there, at that stop sign at the same instant, is stunning.
